I dug this video out of the archives from the first DrupalCamp Michigan in 2011.  While many Drupal developers have a lot of success building websites without a coding environment more complex than a text editor many times more serious tools are required.  My presentation below gives users a basic introduction to debugging Drupal and how you can get started within no more than an hour worth of effort.

[Note: it's likely this video will never work again.]
